2017 SEAT Ateca 1.6L Diesel · DC17 TXE

A single major oil‑leak failure recorded in September 2023 is the only significant defect in an otherwise clean MOT history, and the most recent test on 1 September 2026 passed with only a minor advisory about light oil misting from the nearside rear shock absorber. Apart from that isolated failure, the vehicle has consistently cleared MOT without further failures, indicating that any remedial work undertaken after the 2023 defect has, at least to date, restored the car to a road‑worthy state. At 173,987 miles over roughly nine years the average annual accumulation is about 19,300 miles, which is well above the typical UK passenger‑car usage. The MOTs have been performed annually with no long gaps, suggesting the mileage has been accrued steadily rather than in large, undocumented bursts. Such high mileage accelerates wear on consumables and load‑bearing components, meaning that items such as brake pads, discs, tyre tread, suspension bushings and the drivetrain will be approaching the latter stages of their service lives and should be inspected closely. The 2023 oil‑leak failure (excessive engine oil loss) warrants a thorough visual check for any fresh oil stains around the engine bay, especially near the valve cover, oil filter housing and oil pan seams. Verify that the oil level is correct and that the engine does not exhibit low‑oil warnings or abnormal noises such as ticking or knocking under load, which could indicate incomplete repair or lingering seal issues. The recent advisory about oil mist from the nearside rear shock suggests the damper may be beginning to lose fluid; listen for a faint hissing or squelch when the rear wheel is compressed, feel for uneven rebound, and inspect the shock for any external oil residue or dampness that could affect ride quality and tyre wear. Given the mileage, examine the front and rear brake discs for scoring or excessive thickness loss, and test the pedal for a firm, consistent feel without pulsation, which would hint at warped discs or worn pads. Check the suspension for any looseness, clunking, or uneven tyre wear that could point to degraded bushes or worn shock absorbers, especially on the nearside rear where the oil mist was noted. Finally, assess the clutch engagement point and any vibration during acceleration, as high‑kilometre wear on the clutch assembly and gearbox bearings can become apparent under load. A comprehensive test drive that includes steady‑state cruising, gentle braking, and modest bumps will help confirm whether the vehicle’s major systems remain reliable despite its extensive use.
